Abstract:
Dyes are an important class of pollutants, and their disposal in valuable water resources must be avoided. Various treatment technologies are in use and among them adsorption occupies a prominent place in dye removal. The growing demand for efficient and low-cost treatment methods as well as the importance of adsorption has given rise to low-cost alternative adsorbents. The purpose of this study was first to examine and then to maximize, if possible, the absorbency of modified barley straw, in order to remove basic dyes like Methylene Blue (MB) from substitute wastewater. More specifically pretreated barley straw, with acetone organic solvent, has been used as an adsorbent. The organosolv pretreatment was catalyzed by 0.01-0.035 M H2SO4, at 140-180 oC, for 0-40 min isothermal reaction time, using a 3.75 L batch reactor. The experimental condition combinations were chosen according to the principles of experimental design. The effect of organosolv pretreatment conditions, i.e., reaction time, temperature and catalyst concentration, was investigated using UV-visible spectrophotometry. The applicability of various adsorption kinetic models and isotherm models is demonstrated herein.
